Described is a natural absorbent product. In particular, the described is a miscanthus absorbent product made from densified miscanthus have a density is a range from 17 lbs./ft.3 to 29 lbs./ft.3 and a mean particle size in a range from 0.6 mm to 0.8 mm. Also described are methods of producing of miscanthus absorbent product. The method includes chopping miscanthus stalks to a desired length, processing the chopped miscanthus to break apart the chopped miscanthus, pelletizing the processed miscanthus, and reducing the size of the miscanthus pellets to result in a product having a desired mean particle size.

A method of making a nanocomposite is provided. The method includes dispersing nanocellulose and nano-bentonite in water and mixing to form a mixture. The method includes drying by heating the mixture at a temperature of at least 40? C. to form a dry mixture. The method further includes mixing the dry mixture with an alkylamine to form a nanocomposite composition. The method includes heating the nanocomposite composition at a temperature of at least 100? C. to form a paste. The method includes drying and milling the paste to form the nanocomposite. The nanocellulose is prepared from date-palm tree leaflets. The nano-bentonite is prepared from Saudi Arabia bentonite clay from the Khulays Mine. A method of treating water with the nanocomposite prepared by the method of the present disclosure is also provided.

A method for producing charcoal particles or pellets which use different additives as binders for the biochar pellets. The method includes producing a mixture with charcoal and additives selected from nanocrystalline cellulose, nanocrystalline fibrils, bentonite, and polyvinyl acetate. The mixture is created by mixing one or more of the additives with charcoal or bentonite. The mixture is then processed in a pelletizer device. While processing, the surface of the mixture is sprayed with a liquid. Once turned into pellets by way of the pelletizer device, the resulting pellets are then dried by applying heat to the pellets. The liquid can be water or a solution of water and sodium borate.

A process for the preparation from a partially decomposed organic material like peat a granulated or pelletized sorption medium using low-temperature, thermal activation of the sorption medium to produce a high degree of granule or pellet hardness balanced against an efficacious level of ion-exchange and adsorption capacity, followed by chemical treatment of the thermally-activated sorption material via an acid solution and a salt solution to increase its ion-exchange and adsorption performance while minimizing the transfer of natural impurities found in the sorption medium to an aqueous solution is provided by this invention. The sorption medium of this invention can be used in a variety of aqueous solution treatment processes, such as wastewater treatment.

A method provides a buoyant sheet of compacted water Hyacinth particles having a size of between 1/32 inches and 1/16 inches, and a moisture content 10 percent, and a plurality of dry Hyacinth particles having a size of between 0.001 and 1 inch, and a moisture content 10 percent.

The disclosure provides a method for enhancing liquid absorption capacity and usability of coir pith. The method includes providing dry coir pith, screening the coir pith with predetermined particle size, pasteurizing the coir pith using dry heat followed by moisturizing by mixing a moisturizing solution prepared by mixing distilled water with an antifungal agent or pasteurizing the coir pith using steam. The disclosed method is an organic process for cleaning up liquid spills. The method implements coir pith with particle size 1.0 mm or less in absorbing liquid spills, in a cost-effective and environmentally friendly manner. The disclosure further includes a coir pith composition with enhanced liquid absorption capacity of 0.5-0.6 mL of liquid per mL volume of the coir pith.

A method for processing raw coconut coir pith into fine particles having a size range of from 0.001 mm to 7 mm and the use of such fine particles directly or in formulated form in agricultural, industrial and commercial applications.

This disclosure includes regenerated inorganic fermented beverage stabilization and/or clarification media and a process for such regeneration. Inorganic stabilization and clarification media (for processing beer or the like) may include expanded perlite or other expanded natural glasses, diatomaceous earth, silica gel or other precipitated silicas and compositions that incorporate these materials. Such media may be regenerated individually, together in a mixture or together as part of a composite product. The regenerated media meet the requirements for physical and chemical properties for re-use and replacement of the majority of particulate inorganic filtration media, and inorganic stabilization media consumed in stabilization and clarification processes, and the related regeneration process provides for substantial benefits to brewers through a reduction of costs to purchase and transport stabilization and clarification media, to dispose of spent cake and/or membrane retentate, while providing for substantial reductions in the introduction of soluble impurities into the fermented beverage.

A carbon pyrolyzate material is disclosed, having utility as an adsorbent as well as for energy storage and other applications. The pyrolyzate material comprises microporous carbon derived from low cost naturally-occurring carbohydrate source material such as polysaccharides. In adsorbent applications, the carbon pyrolyzate may for example be produced in a particulate form or a monolithic form, having high density and high pore volume to maximize gas storage and delivery, with the pore size distribution of the carbon pyrolyzate adsorbent being tunable via activation conditions to optimize storage capacity and delivery for specific gases of interest.

Mesoporous activated carbon having a mesopore structure of at least about 10%. In at least some embodiments, the activated carbon may be coconut shell-based. The enhanced activated carbon may have an intraparticle diffusion constant of at least about 40 mg/g/hr.sup.1/2.
